Short answer
A dental implant is an artificial tooth root, usually made of titanium or zirconium oxide (zirconia), placed in the jawbone to support a crown, bridge or denture.34 It may replace one tooth, several teeth or a full arch. Treatment is staged over months because the bone must bond to the implant, and some people first need bone grafting.12 Implants need lifelong cleaning and check-ups to limit the risk of peri-implantitis, so the health of the gums, the bone and general conditions such as diabetes and smoking all affect suitability.36

How dental implants work
An implant has three parts: a threaded post placed in the jawbone, a connector called an abutment, and the visible restoration, which may be a crown, a bridge or a denture.1 The restoration is fixed in place, or with some full-arch designs, clips on and off.
The post works because of osseointegration: the jawbone grows into close contact with the implant surface and anchors it.2 This takes months, which is why treatment is staged rather than done in one visit.
Implants can replace a single tooth, support a bridge across several gaps, or support a full arch on multiple implants, usually four to six.1 Full-arch options are covered on our All-on-4 page.
What may be causing the problem
An implant replaces a tooth; it does not treat the reason the tooth was lost. If that reason is still active, it can threaten the implant too. A dentist will usually look at:
- Gum disease (periodontitis). Active gum disease makes implants a poor option until treated, and a past diagnosis raises the risk of peri-implant disease later.16
- Tooth decay. Extensive decay elsewhere in the mouth may need treatment first.1
- Bone loss. The jaw shrinks after teeth are lost or after gum disease; severe loss may need grafting before an implant.15
- Plaque control. Poor oral hygiene is a reason to delay treatment and a risk factor for later problems.16
- General health. Unmanaged diabetes, smoking, bone disorders and some autoimmune conditions can affect healing.13
Who may be considered
The main requirement is enough healthy jawbone to hold the implant, or bone that can be rebuilt.1 Jaw growth must be complete, so implants are typically considered from around 18.1 Overall health matters, because it affects healing time and how long the implant lasts.3
Who may not benefit or may face additional risk
Alternatives
| Option | How it works | Trade-off |
|---|---|---|
| Tooth-supported bridge | A false tooth anchored to crowns on the neighbouring teeth | Neighbouring teeth are reshaped, which can weaken them1 |
| Removable denture | Rests on the gums, partial or full | May slip or fit poorly; generally does not last as long as implants12 |
| Implant-retained denture | A denture that clips onto implants | Still needs surgery and implant maintenance1 |
A fuller comparison is on implants versus bridges.
No treatment is a legitimate option
Not every gap needs filling. Leaving a gap is a reasonable choice for some people, and a dentist can explain whether neighbouring teeth are likely to drift or the bite change over time.
Procedure, preparation and anaesthesia
Planning includes checking the health of the mouth and the strength of the jawbone,4 and reviewing medical history and medicines.2 People with certain heart conditions or orthopaedic implants may be given antibiotics beforehand.2 The US Food and Drug Administration (FDA) suggests asking which brand and model of implant system will be used and keeping that record.3
Treatment is usually staged:12
- Bone grafting, if needed. Bone may come from the patient, a donor bank, an animal source or a synthetic substitute. A sinus lift adds bone beneath the sinus floor in the upper back jaw.5
- Implant placement. The gum is opened, the bone prepared, the implant placed and the gum stitched.1
- Healing. Osseointegration takes several months.2
- Abutment and restoration. A minor second procedure may expose the implant; the gum heals for at least two weeks before the final tooth is attached.12
In some cases a tooth can be fitted on the same day as the implant.4 Anaesthesia may be local, with sedation, or general; anyone having sedation or general anaesthesia needs someone to take them home.2 See also bone grafting for implants.
Recovery and treatment timeline
| Stage | Typical timing |
|---|---|
| After implant surgery | Swelling, bruising, soreness and minor bleeding; most people feel themselves within about a week12 |
| After a bone graft | Tenderness and swelling settle within a week or two5 |
| Graft maturing | At least three months; large grafts nine to 12 months5 |
| Osseointegration | About three to nine months1 |
| Final restoration | After integration and at least two weeks of gum healing around the abutment2 |
Soft foods are usually advised while the site heals, and stitches often dissolve on their own.2 A temporary tooth or abutment may be worn during the healing months.3
How long implants last
With good care, implants can last many years, but there is no lifetime certainty.4 The restoration on top wears faster than the post: Cleveland Clinic gives around 15 years as typical for crowns and bridges, with wide variation.1
Maintenance is what protects the result. That means twice-daily brushing, cleaning around the implant with interdental brushes, and regular dental and hygiene visits.46
Pain and comfort
With anaesthesia, pain should not be felt during the procedure.1 Options range from local anaesthesia, which numbs only the area being treated, to sedation or general anaesthesia; the choice is agreed with the dental team.2
Afterwards, slight discomfort and swelling are normal. Pain-relieving medicines, and sometimes antibiotics, may be prescribed.12 After grafting, ice, soft foods and keeping the head raised are commonly advised.5
Risks and complications
Mayo Clinic describes the risks as small, and usually minor and easily treated when they occur.2
| Category | Examples |
|---|---|
| Expected temporary effects | Swelling of the gums and face, bruising, pain at the site, minor bleeding2 |
| Recognised complications | Infection; failure of the bone to bond; abutment screw loosening; a bite that feels wrong; peri-implant mucositis and peri-implantitis236 |
| Rare serious complications | Nerve injury causing pain, numbness or tingling; damage to neighbouring teeth or blood vessels; sinus perforation in the upper jaw; jaw fracture23 |
Peri-implant mucositis is inflammation of the gum around an implant without bone loss; it may be reversible if treated early. Peri-implantitis also involves loss of the supporting bone and usually needs surgical treatment.6 Risk factors include previous gum disease, poor plaque control, smoking and diabetes.6 If an implant fails to integrate, it is removed and placement can be tried again after about three months.2 See dental implant failure.

How strong is the evidence?
| Claim | Vireon assessment | What supports it | Important limitation |
|---|---|---|---|
| Most implants integrate and function | Moderate | Academic centre and regulator information23 | Results depend on bone, health and maintenance; figures vary between studies |
| Smoking reduces healing and long-term success | Moderate | Regulator and academic centre guidance23 | Size of the effect varies with amount smoked |
| Uncontrolled diabetes raises complication risk | Limited | Regulator guidance; professional society information36 | Well-controlled diabetes may carry less risk |
| Regular maintenance helps prevent peri-implant disease | Moderate | Professional society and dental charity guidance46 | Optimal recall interval is individual |
| Bone grafting allows implants where bone is deficient | Moderate | Academic centre information25 | Graft outcomes vary by type, site and smoking |
| Zirconia performs as well as titanium long term | Insufficient | Both are established materials3 | Long-term comparative data are limited |
This page draws on regulator, academic centre and professional society guidance. Published success and complication rates differ with how failure is defined, how long patients are followed, and who is lost to follow-up, so single headline percentages are best treated with caution.
Materials, systems and red flags
Most implant systems are titanium or zirconium oxide; titanium alloys, other alloys and ceramics are also used, and materials are tested for biocompatibility.3 Claims that one material or brand is clearly superior deserve scrutiny, because long-term head-to-head evidence is limited. The FDA advises asking which brand and model will be used and keeping that record, which helps any dentist who treats you later.3
Treatment-specific red flags include:
- a plan made without assessing the gums, the jawbone and medical history;24
- no record of the implant brand and model offered;3
- no clear arrangements for follow-up or for problems after you return home.7
Our medical travel red flags page covers wider warning signs.
Cost drivers and what a quote should include
Cost depends on the number of implants, whether bone grafting or a sinus lift is needed, the type of restoration, the implant system, the anaesthesia used, and how many visits are required. A clear written quote would normally state:
- the diagnosis and treatment plan, stage by stage;
- the implant brand and model, and the restoration material;
- temporary teeth during healing;
- whether follow-up care is included;7
- what happens if an implant fails to integrate.
See reading a treatment quote.
If you are travelling for treatment
- Staged treatment usually means more than one trip: surgery, then the final teeth months later.1
- Assessment, surgery and fitting all need to be done in person.
- Speaking to your regular dentist before deciding is strongly recommended, and they will often provide maintenance afterwards.7
- Correcting problems after you return home can be costly, so agree in writing who handles complications.7
- Bring home a record of the implant brand and model, and your treatment notes.3
Questions worth asking a clinician
- Why did I lose this tooth, and is that cause under control?
- Is there enough bone, or will I need grafting or a sinus lift?
- Which implant system and material do you propose, and why?
- How long will each stage take, and how many visits are needed?
- How should I clean it, and how often should it be checked?
Frequently asked questions
Does getting a dental implant hurt?
Pain should not be felt during surgery under anaesthesia; afterwards, slight discomfort and swelling are normal.1
How long does the whole process take?
Usually several months, because osseointegration takes about three to nine months; grafting adds more time.15
When can I go back to work and eat normally?
Most people feel like themselves within about a week, though soft foods are advised while the site heals.12 The right time to return to work depends on the extent of surgery and the anaesthesia used.
Can I have teeth fitted on the same day?
Sometimes, depending on the case.4 Often a healing period comes first, with a temporary tooth.
How long do implants last?
With good care they can last many years, though the crown or bridge on top may need replacing.14
Do implants affect medical scans?
They can distort MRI (magnetic resonance imaging) and X-ray images, so tell staff about them before imaging; the FDA is not aware of harm from these scans.3
Bottom line
An implant is a long-term commitment rather than a single procedure. Its success depends as much on treating the cause of tooth loss, the state of the bone and daily cleaning as on the surgery itself.
